GAS BURNER.

Application filed March '2, 1928. Serial No. 258,484.

My invention relates to gas burners, particularly burners adapted foruse in gas water heaters. It has for its principal ob ects to providethe several burner tips of a ring type burner with means for properlydlrecting the several flames, to make it possible for the flame of oneburner tip to be ignited by the flame of an adjacent tip, to protectsaid burner tips from drippings, to prevent accidental extinguishing ofthe' flame and to provide a construction that is easily assembled anddisassembled and easily installed.

The invention consists principally in the gas burner and in the partsand combinations and arrangements of parts hereinafter de scribed andclaimed.

An annular burner ring 1 has a plurality of burner tips 2 arranged onitsupper surface. Each burner tip may have a screwthreaded lower endport-ion 3 threaded into said burner ring. Each tip 2 has a central bore4 permitting gas or other fuel to pass, therethrough. The lower endportion of the bore 4 of each tip 2 has a constricted neck portion 5 andradial cross bores 6 opening into the longitudinal bore 4 above itsconstricted neck portion, permitting air to enter the burner tip and mixwith the fuel.

Disposed inside the circle of the burner tips '2 is a bafiie ring 7 thatflares upwardly and whose upper portion overhangs or extends outwardlbeyond the line of the burner tips. Said ba e ring or flame spreader 7is proform of vided with supporting legs 8 having curved lower endportions fitting the burner ring 1.

The burner ring 1 has a diametrically extending cross piece 9 and thebaflle ring 7 has a similar cross piece 10, preferably disposed at rightangles to the burner ring cross piece 9 when the parts are assembled. Abolt 11 extends through said cross pieces and is provided with a nut 12;so that by tightening said nut the parts are held in assembled position.

The burner is particularly adapted for use in connection with hot waterheaters, in which case it is disposed beneath the water heating element,as a boiler.

Fig. 6 illustrates a boiler 13 provided with a central flue 14 in whichis disposed a heating element 15 for the water. The diameter of thecircle of burner tips 2 is approximately the diameter of the annularflue space between the boiler 13 and the heating element The baflle ringspreads the flame and protects the burner tips and the burner ring fromany drippings. The ring makes it possible for a flame to pass from onetip to the next tip; whereas without such a ring it would be necessaryto light each tip separately. No matter from what direction a. draft orgust of air may come, some, at least of the burner tips are protectedtherefrom. Accordingly, the flame of the burner will never be completelyextinguished; and any tips whose flames may be extinguished will berelighted by the flames of adjacent tips. The baflle ring also preventsextinguishment of the flame due to high gas pressure.

The invention is also adapted for embodiment in different constructions.Fig. 7 shows an elevation of a construction having a straight fuelsupply pipe 1 with a plurality of burner tips 2 arranged along its top.A bafile strip 7 is disposed with its lower edge along one side of theline of burner tips and the upper edge of said bafilestrip overhangs theburner tips, to prevent anything from dripping on said tips. The bafllestrip has supporting leg portions 8 that terminate in half-rings 20 thatengage the fuel supply pipe 1*. Cooperating half-rings 21 are secured t0the first half-rings 20 to hold the'parts supporting legs onsaid bafilering having together. curved lower ends fitting said burner ring,
